STEREOSCOPIC GAMIERA.

No. erases;

To all whom it may concern:

Be it known that I, Mansion VINCENT, residing at, Geneva, Switzerland, have invented a new and useful Stereoscopic Camera of which the following is a specification.

My invention relates to improvements in stereoscopic cameras, and the objects of my improvements are, first, to provide means so as toproduce a crossing of the rays coming from the two objectives in such that the picture formed b r the left hand obl ective is reproduced on t e right side of the sensitive plate, and the picture right, hand objective on ,the left side of said plate, and, second, to create a collapsible camera capable of being folded into a small compass, and to secure other advantages and results as willbe hereinafter explained.

he trans osition of the light rays which produce t is "two parts of the stereoscopic picture avoids the necessity for cutting and reversing the negative in the manner heretofore common.

In the accom anying drawings like letters of reference indicate similar parts throughout the several views. i

Figure l is a horizontal section of the camera; Fig. is a similar sectional view of a collapsible camera when folded up and Fig. 3 is a detail.

he camera is formed by a box A which has inits front side two openi intended to receive the two object glasses, and in its back side a large opening containing a grooved frame I) which serves to receive and hold the ground .glass, and afterwards the sensitive plate holder.

E and H are two mirrors which rcflect'thc rays coming through the openings B, C, at the front and direct them forward in crossin lines as shown in Fig. so that they impinge upon the reflectors Fand I, the rays from the reflector E crossing those l'rom the ing through the opening B or through the object glass therein and is in a plane parallel with the front reflector F and the reflectors II and l are similarly related-to the O. The reflectors I and F direct the rays in parallel lincsbac]: to the ground glasspr sensitive plate lying in or in connection with t e frame D.

K are screens to prevent disadvantageous light reflections in the camera, the perforagiven by the opening 5 l l I l Specification of Letters Patent.

of passage of light rays from one reflector to t e other.

The camera shown in Fig. 2 is similar to the one. shown in Fig. 1 but it is rendered collapsible by interposition of a bellowsL between the front and back sides of the camera, which are united by telescopic guiding means m, n, and by slidin braces o. In this arrangement the screens are partly flexible.

Fig. 3 shows the arrangement of an ad'usbable mirror. Generally it will suffice to ave one of the mirrors adjustable. The mirror C is supported by three screws 1' and held thereupon by springs s. Bv turning said screws the mirror can be slightly inclined in any direction and thus a discordancein the position of the picture halves be readily corrected. v

Having thus described I claim as new is:

1. In a stereoscopic camera, the combiner tion with the box andobject glasses, of reflectors and means for adjusting said reflectors to change the planes at which they lie in said box, comprising springs and adjusting screws opposed to said springs, said sprin the invention, what holding said reflectors against the inner en 8 of said plates.

2. In a stereoscopic camera, the combinawith the camera box, the sides of the bo being formed of bellows, interior screens in the box and having light openings at the front, of a pair of oppositely inclined "reflectors adapted to direct the light rays from one reflector across those from the other reflector, means, for tilting the reflectors, a pair of reflectors at the front of said box adapted to receive the light rays from the first said reflectors and direct them in parallel lines to the back of said box, means to hold a sensitive plate at said back of the box, in position to receive the. transposed light rays, interior screens having rigid portions with openings dis )osed to allow the passage of light rays when the bellows and the remaining portions of the screens being flexible to allow collapsing of the camera box.

in testimony whereof I have hereunto set I my hand in presence of two subscribing witnesses.
